WRENCH.

Specification of Letters Patent.

Patented April 24, 1906.

Application filed May 81, 1905. Serial No. 263,198.

To all whom, it m my concern:

Be it known that I, VVILLIs F. ONEILL, a citizen of the United States, residing at I/Vaukegan, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in Trenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to wrenches.

One object of the invention is to provide an exceedingly simple, inexpensive, durable, and efficient wrench of the character named.

Another object of the invention is to provide a nut-wrench embodying among other characteristics the feature of having a dog engaged directly to the operating-lever.

With these and other objects in view, the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particu larly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

The accompanying drawing illustrates an elevation of my invention, partly in section, illustrating the locking-dog in engagement with the teeth of the stock of the wrench, the dotted lines illustrating the dog swung outwardly from engagement with the teeth.

Referring now more particularly to the accompanying drawing, the reference character 1 designates the stock of the wrench having the fixed jaw 2 at one end and the teeth 3 upon its inner face, which extend nearly throughout the length of the stock.

The reference character 4 designates the movable j aw having an opening therethrough whereby it may he slid ably mounted upon the stock. It will be observed that the jaw-face 5 of the movable face is closed and that the inner and lower faces of the said jaw are opened, there being an operating-lever 6 pivotally mounted in the inner open side of the movable aw by means of a suitable pivot-pin 7. This operating-lever is designed to be brought down at its inner end within the inner side and lower openings of the movable jaw, so that the dog 8, secured to the inner face of the operating lever, may be brought into engagement with the teeth 3 of the stock. This dog 8 may or may not be detachably secured to the inner face of the operating-lever 6. However, the said dog, as shown in the drawing, consists of a short piece of metal or other suitable material and has its rear end bent downwardly from the end face of the operating-lever, as indicated by the reference character 9, so that it will positively engage the teeth 3 of the stock. As shown in the drawing, the dog is secured to the end face of the operating-lever by means of a rivet or the like 10, by reason of which an old stock or dog may be replaced by a new one.

In order to prevent the movable jaw becoming disengaged from the outer end of the stock, I provide a strap 11 upon one side face of the stock near the outer end thereof.

From the foregoing it will be understood that when it is desired to manipulate the wrench it is simply necessary to bring the operating-lever down upon the inner face of the stock and prevent backward movement of the movable jaw. It will be also seen that my improved wrench consists of a very few elements and is therefore of an exceedinglyinexpensive nature as compared with the expensiveness of the type of wrenches embodying springs and other connections. Another feature to be observed is that the movable jaw may be moved backwardly and forwardly upon the stock by means of the operating-lever.

What is claimed is 1. A wrench comprising a stock having a fixed jaw at one of its ends, a series of rackteeth formed on the inner edgeface of said stock, a movable jaw slidably mounted upon the stock, a lever pivoted at one of its ends in said movable jaw, and a dog secured to said lever, said dog comprising a plate having its free end turned laterally and arranged for engagement with the teeth of said stock.

2. A wrench comprising a stock having a fixed jaw at one end and provided upon its inner edge face with a series of rack-teeth, a ally from said lever and arranged for engagemovable jaw slidably mounted upon the ment with teeth on said stock. 10 stock, a lever pivotally mounted at one of its In testimony whereof I affix my signature ends in said movable jaw, and a dog comin presence of two witnesses.
